If you still play the game and still tweak it even after it's been abandoned by the company, and if you have an Nvidia graphics card, you really want to enable the SGSSAA fsaa.

For those wondering what it is, here is a very good description of SGSSAA, how it works and applies:

To enable that fsaa technique on your graphics card, do the following:

1. Download and install the nvidia inspector:

2. Choose Skyrim from the game list.
3. Change Antialisasing mode to Override any application settings, then select 2x sparse grid supersampling and 2x Multisampling options.
4. Change lod bias to -0.500 and negative lod bias to allow.

Enjoy some cool graphics!

Its impossible to make a game look as "intended" by using a third party tool to change some graphics options that are normally inaccessible, when the game wasn't designed, or intended to run with it in the first place.

lol no, it's possible. Just try it.
